A novel one-pot oxidative cyclization of 2′-amino and 2′-hydroxychalcones employing FeCl3·6H2O-methanol. Synthesis of 4-alkoxy-2-aryl-quinolines and flavones

A simple, inexpensive, and efficient oxidative cyclization of 2′-amino and 2′-hydroxychalcones has been carried out by employing FeCl3·6H2O-methanol under mild conditions. This method has been investigated for the synthesis of 2-(1,3-diphenyl-1H-pyrazol-4-yl)-4-methoxyquinolines.
